In addition, the clouds have thousands of physical and virtual machines that are constantly being added or removed that the current access control mechanisms cannot handle (Ko, Popa, Ratnasamy, Stoica, & Yu, 2010) Another cloud computi ng security issue is safer store of sensiti! ve information. One of the hard-hitting issues is where to figure the sensitive data. In the current shared environments there is no guarantee of the fairness of the leaf node environment.
